Please Note: Some wrinkling should be expected when installing expandable pool liner

Do not use an expandable liner on a pool not built specifically to use one.

EXPANDABLE OVERLAP POOL LINERS: The expandable pool liner is an overlap liner that has walls that are taller than normal to accommodate for the extra vinyl needed for a deep end or deep middle swimming area. This type of pool liner will allow up to an extra 2 feet of water depth. This is most common on round above ground swimming pools. Expandable liners can only be installed in oval pools that have no buttress straps that run across the middle. Pools with straps cannot be dug out in the middle. Unless you are a professional pool installer, expect wrinkles or folds in the pool liner after installation.

Pool liner is fine. Just like most of them. Only reviewing because they are so hard to find on-line. PcPools is one of the only stores to have one, it was in-stock and the price was GREAT with free shipping!
